Geo 612 setup Question

[Zach.Attack6]

Im setting up my Geo 612 calcium reactor and wondering if I can use a mag 5 or simiar pump to feed the reactor instead of the maxi jet 1200 or aqua lifter option because i want to run phosban reactor and calcium reactor on the same pump and just T off with two valves on each side of the T fitting

as long as you can get steady pressure you can feed it how ever you want.
